From 51f82a2b128131c411880aed2cb802b166fe3445 Mon Sep 17 00:00:00 2001 From: Denis Cheng Date: Wed, 21 May 2008 17:34:32 -0700 Subject: [PATCH] net/ipv4/arp.c: Use common hex_asc helpers Here the local hexbuf is a duplicate of global const char hex_asc from lib/hexdump.c, except the hex letters' cases: const char hexbuf[] = "0123456789ABCDEF"; const char hex_asc[] = "0123456789abcdef"; and here to print HW addresses, the hex cases are not significant. Thanks to Harvey Harrison to introduce the hex_asc_hi/hex_asc_lo helpers. Signed-off-by: Denis Cheng Signed-off-by: Harvey Harrison Signed-off-by: David S.
